Then you can probably look at the code and see how the developer handles the colliders. Stopping before running into obstacles is only part of the solution for an autopilot. Its likely they realized in developing the plugin that scanning the immediate area for a route around the obstacle was too complex to tackle, so they opted to put it away for another day.
